In order to chase with the College of DuPage, one must fill out a waiver form that states that the participant fully understands and accepts the risks associated with storm chasing. It is entirely possible that some of you may have a somewhat distorted view of storm chasing. Perhaps there are those who have not thought through some of the risks before. So, in order to ensure that you fully understand the risks involved, and to make sure that all of our participants do not have the wrong impression on what storm chasing entails, we ask you to read the following pages carefully. Should you have additional concerns or questions, please do not hesitate to contact us. Remember, your safety depends on your understanding the hazards of storm chasing and the methods of minimizing the risks. Storm chasing can stir up different feelings for different people. There are hundreds if not thousands of people that storm chase in a given year, yet the reason they do so can vary widely. Some are very involved in thunderstorm or tornado research and they chase so that they can witness the Nature’s processes first-hand. Others can be called “yahoos” - people who chase in a careless or reckless nature hoping to drive into a tornado or just get as close as possible to get the ultimate thrill. There is an entire spectrum of possibilities in-between as well, such as ordinary folks paying money to be tourists just hoping to witness a tornado at some point in their lives. How you feel about your storm chase experience has a lot to do with how the chase measured up to your expectations. If you expected to see dozens of tornadoes and failed to see one, chances are you will feel very disappointed. If you went into the experience looking forward to seeing a variety of weather features and enjoying the company of others, you will come out of the experience with a more favorable impression. Therefore, we must first talk about what to reasonably expect weather-wise. Here at the College of DuPage, we are forced to choose the time of our chase trips well in advance of the departure date. This is due to the fact that we must get 18 people with different schedules and lives together at the same time. We must rent the vans that we use and the instructors must make alternate arrangements for the other courses we teach. We are simply not able to chase when the conditions look best for tornadoes, therefore poor weather conditions for thunderstorms could very well face us on one or more of our trips! We are simply at the mercy of the weather. Our chase dates happen to coincide with dates that, at least climatologically, offer the best chance to encounter tornadoes. However, any given year can deviate from climatology, and those deviations are beyond our ability to forecast. Last year (2004), every one of our four trips encountered a tornado. That was the first time in the history of the COD chase program that every one who went with us saw a tornado. Some of the tornadoes last year were better than others, but at least everybody walked away from the experience being able to say they saw a incredible tornadic storm. There have been some trips in years past when no thunderstorms (let alone tornadoes) were spotted. On the other extreme, there have been trips where ten tornadoes were seen in just one day! What happens on a particular trip simply depends on the weather patterns for that week, and our ability to forecast the weather accurately in order to put ourselves in the right place at the right time to witness Mother Nature at her worst. Simply put, we can not guarantee you a tornado. We can not even guarantee rain! The only thing we can promise is to take the group to the location where we think the best place for thunderstorms will be that day. Even on days when thunderstorms and tornadoes are occurring, other factors such as the road network, hills, trees, and other events completely out of our control can inhibit our ability to get within sight of a tornado. It is not easy to see a tornado. On days when thunderstorms will not happen within our reach, we will try to do something fun as a group – such as go to a National Park, a museum, or experience part of Americana. However, these kind of down days could be spent traveling many hours to get us to an area where storms might form the next day. While we strive to make our trips enjoyable for everybody, we can not guarantee that you will be entertained constantly throughout the entire chase trip. Your participation and attitude is the single most important factor in creating an enjoyable trip. Risks Associated with Storm Chasing Driving One of the most significant risks associated with storm chasing is the simple act of driving. Normal driving presents many risks on a daily basis. During a storm chase, the risks due to driving increase. Most drivers tend to get distracted when they want to look at the storm instead of the paying full attention to the driving chore. Some drivers could get nervous and begin to race home to attend to their children and belongings, or to get their car out of the way of dangerous hail. Finally, storm chase yahoos could be speeding down the road (and not necessarily in the correct lane) in order to get in a close position to the storm. In short, driving gets even more hazardous near thunderstorms. The road conditions can also take a turn for the worse. For instance, hail can cover the ground completely. Heavy downpours of rain can leave ponds of water on the roadway and lead to hydroplaning if the driver is not careful. The storm could have knocked down power lines, trees, or other debris onto the roadway. Torrential rainfall can reduce visibility to near zero. Finally, flash flooding could turn our road into a river! We minimize these risks by using only well-qualified and experienced drivers during the most hazardous conditions. Lightning Lightning is an obvious hazard. Lightning kills dozens of people every year, yet most people hear the statistics that the odds are very low to be hit by lightning. One statistic says that a person has a one in 600,000 chance of being hit by lightning. The problem with that statistic is it is calculated for the general public. The odds of a storm chaser being struck are higher because we behave in ways that the general public does not – we go outside and attempt to get close to a thunderstorm! Because our purpose is to experience and view a thunderstorm, there is little we can do to alleviate this risk. We are seeking out thunderstorms, and there is no safe place to be relative to a thunderstorm to avoid lightning. In order for a thunderstorm to be called a thunderstorm, it must have lightning! Lightning does not need to give warning signs before it strikes, so it can strike you in the blink of an eye. Because this is a serious hazard we do try to minimize the risk where possible. It is always the prerogative of the student to remain in the van should lightning be perceived as a risk. When lightning appears too close or too frequent, the instructor may order the chase participants into the vehicle. Vehicles offer good protection from lightning. The exterior metal of the vehicle will allow the electricity to flow around the shell and go to ground, keeping the occupants safe. One problem with this is our vehicles have many antenna cables going into the van from the outside. Lightning can travel inside the van along these cables, and anybody touching them or the radios could receive quite a shock. When you are in the vans, make sure you are not in contact with these cables. Remember, lightning is unpredictable and one stroke is all it takes to be deadly. Treat lightning with respect. Hail Hail was already mentioned as a hazard for driving. It is also a hazard to you should you be standing outside when large hail begins to fall! A hailstone about the size of a golf ball can be falling at a speed of nearly 80 miles an hour. If it strikes you on top of the head, that can injure you seriously (if not kill you). Hail does not kill many people per year, but fatalities have happened in the past when people are outside as hail begins to fall. Hail can also cause damage to the vehicle (exterior damage, broken glass, etc.) that you are riding in. Fortunately, large hail falls in a particular region of a thunderstorm that can often be avoided. However, there could be times when the road network, storm movement, or other factors put us in the wrong place at the wrong time. Gusty Winds Strong winds occur near thunderstorms, and these winds are capable of knocking down trees, power lines, or picking up debris that can fly through the air and cause injury. When the winds get strong or are about to be strong, nobody will be allowed outside of the vans. Tornado It may seem surprising to you that the most violent hazard contained in thunderstorms is last on the list of hazards! It is obvious to everyone that tornadoes are a hazard and the only safe place to be near a tornado is underground in a basement or storm cellar.
